Specification of Letters Patent. Patented. June 8, 1915.

Application filed. June 3, 1912. Serial No. 701,206.

To all whom it may concern was, a subject of His Majesty the King of Great Britain, residing at London, in the county of London England, have invented certain new and useful Improvements in which the following is a specification.

This invention relates to improvements in and connected with windows and has reference to windows of the type wherein the sashes are pivoted.

The present invention has for its object to improve and simplify the construction of such windows and consists in various improvements in construction and detail designed to render such windows convenient and effective in operation and of comparatively inexpensive construction.

The accompanying drawings illustrate my invention Figure 1 being a front elevational view of the window with one of the sashes partly opened for ventilating purposes. Fig. 2 a side sectional view on line A. B. C. D. E. F. of Fig. 1. Figs. 3 and 4 face views illustrating the specialform of pivot employed. Fig. 5 is an elevational' view and- Fig. 6 a section on line G. H. of Fig. 5 showing a means for maintaining the window sash at certain predetermined angles.

Referring to these drawings wherein like letters of reference indicate corresponding parts wherever occurring, the numeral 1 designates the window frame and 2 the supplemental stiles to which the sashes 3 are pivoted. The supplemental stiles pivotally connected to one sash are connected to the supplemental stiles pivotally connected to the cooperating sash by means of cords or the like 4 passing over pulleys 5 so that the one window balances the other. The pivotal connections which forms no part of my invention but, by means of which the sashes pivot 8 and has an exactly similar cut away or recessed portion 11 so that when the two members 6 and 7 are fitted together the one is capable of turning relative to the other through an angle of90. This form of pivotal connection has the advantage that when the sashes are in the normal closed or vertical posltion there is no gap presented to the view.

In order to enable the sashes to be held at an angle to the vertical for ventilating purposes I provide the fitting 12 which is provided with slots 13 slidable respectively upon the pin 14 and the thumb screw 15 carried upon a fixed plate 16 attached to the window frame. Thus the fitting 12 is capable of adjustment within the limits of the slots 13 and the thumb nut or thumb screw 15 serves to secure the fitting 12 in the desired position. A suitable knob 17 may be provided as shown to facilitate the adjustment. The fitting 12 carires in any suitable manner the arms 18 which are pivotally or loosely connected and are provided at their free ends with hooks 19 which in operation engage pins or hooks 20 provided upon the sashes. In order to provide for the limited adjustment of the effective lengths of the cords 4 the fittings 21 to which they are connected are provided with screw threaded ends so that such fittings can be screwed more or less into the supplemental stiles 2. and if it is desirable to provide for the possibility of having both sashes located at the top of the window the cords may be entirely disconnected from supplemental stiles and anchored to a suitably located hook on the window frame. Further in order to facilitate repairs and redecoration of the sashes the cords can be entirelydisconnected from the sashes and the sashes removed. The sashes 3 may also be held at certain predetermined angles to the frame by the method in Figs. 5 and 6. A well fitting 21 is housed in the member 6 and secured thereto by screws 22 passing through the lugs23 on the fitting. This well contains a piston 24, with a hemi-spherical or other suitably shaped head 25 and a spring 26. In the member 7 I are three (there may be more or less) bores 27 equidistant from the axis of rotation and at the same distance therefrom as the piston 24. When the sash 3 is swung from the vertical position between the supplemental stiles 2, the hemispherical or other suitably shaped head 25 of the piston 24 is forced successively into the bores 27 in any one of which it will rest if the turning effort is discontinued. The bores 27 may be in the member 6 and the piston 24 in the member 7 stationary plate, 7 a movable plate having slots the slots adapted to accommodate the I pins,- fer fholding the movable plate *infto engagement With the fixed plate, a pinearried' by each sash, arms hav ing hooked ends,
